ssh - gitlab 5.1 新規ユーザー用に新しく追加された ssh キーは、1 日後にのみ機能します (プッシュ/クローン)

Question

私のユーザーは奇妙なことを経験します。彼らが新しいキーを追加すると、リポジトリをプッシュまたはクローンするのは別の日にしか機能しません。データベースを調べたところ、authorized_keys ファイルとキーがそこにありました。ログにも何も表示されません。とても迷惑です。誰かがそれを解決する方法を知っていますか?

My users experience strange thing. When they add their new key, it works only another day to push or clone a repository. I looked into database and authorized_keys file and keys are there.
